To all 'whom t may @o1/wem Be-it known that l., FRANK YVririNiir, s citizen of the United States, residing :it Hubbard llloeds, in the County of Cook and 'State of Illniois, have invent-ed certain new and useful Improvements; in Roller Bearings, of which the following is a specific'atien.

My invention relates 'to roller bearing: and more espeeiallyzto bearings of the tyre comprising inner and outer bearing nieiii bers, one rotatable with respect to the other, and formed With opposed eonieiil faces lr'ietvveen which are arranged ri spaced eireular series dise rollers, that is, rollers the Widtl'i ortliiekness of which isless 'than their diameter and in which one bearing member islzidjustuble longitudinally to 'miie up loose4 ness in assembly or which may be developed through wear of the parts.

The obje-et of the invention, generally`A speaking, is to provide certain improve.A

Referring to the drawings, designates the outer bearing member of the bearing which may be tittcd into the housing of a wheel or other machine part indicated in fragmentary dotted outline at 2G'. 27 is the inner bearing,r member shown as arranged on a shaftf28. The bearing members S25, 27 are formed with opposed parallel7 conical faces 29, 30 between which are a plurality of cylindrical rollers arranged in a plurality of spaced circular series. Four series of rollers are shown, the rollers of which are designated 31, 32, 33 and 34. The rollers are supported in carrying rings 35, 3G, 37 and y3 These rings are arranged in pairs, back to back so to speak, and are formed with spacing lugs 39 which intervene be` tween .the several rollers so as to keep them from touching, the spacing lugs being formed at the `inner edges of the rings and in the case of each pair of rings the lugs 0n one ring project in the opposite direction .from the lugs on the other ring, all of the lugs being substantially parallel with and spaced a short distance from the surface''l of the inner bearing member 27. The carrying rings of each pair are made from identical blanks. One of these blanks is illustrated in Fig. 3 and designated 40. In .manufacturing the' rings the blanks are first cut to the form shown in Fig. 'lhe lugs 41 projecting inwardly fromA the inner edge o't' the r'ing are then bent out at right angles to the ring. Thereupon the rings are pressed to a conical conguration, some in one direction and others in the other direction, s0 that the rings can be fitted together inv pairs as rights and lefts, so to speak. The .advantage of this procedure is that the rings of each pair of rings can be cut out and formed by the same dies and tools. But the arrangement ot the roller carrying rings in pairs back to back has another advantage. ,It is necessary te interpose between the two double series ot roliers,a spacing ring which will prevent the'adjacent rollers from coming into contact with each other. Such spacing ring is shown at 42 in Figs. 1 and 7. A spacing ring maybe used in this connection of Whatever thickness may be required to occupy the space between the rollers when the latter are adjusted to their proper places on the outer bearing member. If desired, the spacing ring 42 may be made of very considerable thickness so as to give a wide tread bearing.

The rollers are preferably made of sheet metal formed by pressing to the conliguration shown in Figs. 9 and ,10. A disc is first cut out ofesheet metal and is then pressed into concavo-convex form with its edges bent over to form a Harige 43 projecting from the disc in the same direction as the concavity 44. The concave-convex configuration of the web of the roller increases (he strength of the roller and at the same time gives it a certain capacity for yield` ing under stresses which might` otherwise be destructive. A crushing load on the rol'- ler deflects it equally across the tread inf stead of tending to break the web and bend the llange as with a roller of this type having a. Vtlat Web. If a burr is formed in blanking the disc the roller will be pressed so that the burred edge will be on the in side orf theroller, not along its bearing face. rl'he rollers, it will be observed, have hol lows or eoncavities on both sides which will serve to retain grease.

The rollers and their carrying and spacing `rings are retained in the outer bearing member' 25 by a pair of'conical retaining rings 45, 46, ring 45 fitting into a recess 47 formed at the small end et the.. conical surface 29 and thcnfing 4G being driven into a recess 48 formed at the other end of the bearing member and against a shoulder 49. lhe intention is that the engagement bc tween the ring 46 and the bearing member should be permanent, to all intents and purposes, so that after this ring has been driven into place the outer bearing member and the rollers and their carrying, spacing and retaining rings will constitute a single unit ry strutture. For this purpose either the s r` face of reces; 48 or the outer edge of the ring 46 (Fig. 8) is knurled or milled or otherwise ronghened; may be so treated. It is particularly advantageous to knurl thc surface 48 of the outer bearing member, as the member is of hardened str-el and the knurling will cut thc, ring :is it is driven into place. Once the ring is in place it will not rotate with the rollers and is removable from the bearing Mii] or both such surfaces'` membe; only with Conadereih dhmlljv.
